This is just my first graph. Tell me what you think. I know I'm missing something, but at least I've made it this far!!!

Running 3 subs.

HSU VFT3 HO w/Turbo
HSU VFT3 MKII
HSU MBM-12

Moved 1 of the subs around, and here's the 2nd attempt.

Any particular reason you’re using three mismatched subs? That’s usually not a good thing.

Wayne

Wow, pretty good for just moving one of the subs arround. Looks like all you need to do is tame a few bumps. Now if I understand the HSU MBM concept, is the MBM connected to just the HO or is it tied into both the HO and the MKII?

Well, the MBM and the VFT3 HO w/Turbo are designed to be used together.

I previously owned the VFT3 MKII, and decided to replace it with the HO and MBM. Haven't sold the MKII yet so I decided to try all 3 of them together.

Hi Wayne,
He has three subs but effectively they are two. The HSU MBM (mid base module) is fed the upper side of the frequency band and I'm guessing the HO is fed the lower. The VTF3 MKII is the wild card I would guess. I am surprised the graph isn't all over the place though.
I wonder what the freq decay charts would look like?

And the LF Decay

You are correct John.

The MBM is getting everything from 80hz down to 50hz. The HO and the MKII are both being fed everything from 60hz and below.

So, does anyone have any feedback on these graphs? This is my first outing with REW and the 1124p.

Thanks,
Nick

In my opinion, it would be more useful to also have measurement for your mains+subs because you may be able to get a much nicer curves for frequencies over 50Hz with your mains.
For instance, the 85Hz problem could disappear when using the mains.

Just my 2 cents
